Every lab is different. The math is not.
Eight regulated industries. One calibration problem.
The mathematics of a calibration curve does not care what industry you are in. What changes is who inspects you, which criteria apply, and how expensive an indefensible record becomes. WLTR configures to your methods and your regulators.
Seventy-plus VOCs per run, ICV/CCV burden, and state auditors who ask for the curve behind a five-year-old result.
- EPA 8260/8270
- ISO/IEC 17025
- NELAP
- GMP
- ALCOA+
- 21 CFR Part 11
Batch release rides on impurity and nitrosamine results, and calibrations are accepted on system suitability and a correlation coefficient.
Every calibration level scored, every model compared, and an attributable record ready for the next FDA inspection.
- 21 CFR 211
- ICH Q2(R2)
- Nitrosamines
Small utility labs report PFAS, VOC and DBP results against limits as low as 4 parts per trillion, with certification audits on a fixed cycle.
Low-end accuracy checked on every calibration, and a documented record behind every compliance result reported to the state.
- SDWA
- 40 CFR 136
- PFAS
Young labs scaling fast under shifting state rules, with audit maturity expected to appear overnight.
An audit-defensible calibration process out of the box: evidence discipline without building a QA department first.
- State regulation
- Potency
- Pesticides
Contaminant and residue panels carry brand-level consequences; a soft calibration invalidates entire batches of results.
Point-level acceptance checks and ICV verification on every panel, documented before results ship.
- FSMA
- Contaminants
- Residues
Potency and contaminant results decide label claims and lot release across botanicals, gummies, softgels and powders.
Every analyte checked across the calibration range, with records that stand up to 21 CFR 111 and customer audits.
- 21 CFR 111
- Botanicals
- Contaminants
Every calibration is potential courtroom evidence. Defense experts subpoena curves, exclusions and the analyst’s judgment.
Immutable source records and owned exclusions make cross-examination a walkthrough of the evidence, not a search for it.
